Method for producing hydrocarbons having two carbon atoms

摘要

A method for producing hydrocarbons having two carbon atoms, which comprises introducing methane gas into a reactor downwardly from the top, the reactor comprising a pair of reactor walls extending vertically and facing each other, one of the walls being maintained at a high temperature and the other being maintained at a low temperature, so that the methane gas is dimerized primarily through the dehydrogenation on the surface of the high temperature wall to form C2 hydrocarbons and hydrogen, and the C2 hydrocarbons are preferentially diffused and transferred to the low temperature wall side by thermal diffusion effects.
